This album is still soft music, you can use the 40 minutes Put down the work you do good, to rest, quiet meditation. The music include θ waves , please listen to music with headset. First track is Canon ,the next song is the Big ben , music will bring you back to childhood time. Lunch break, swing, tree breeze, the yellow lines, are Part of school life. At night, my mother would tell stories in bed, listen Mozart's music . fell asleep. Good night!
